I To all whom it may concern,.-

other connections W1 .drawn from the well.

v Be it known that I, CLARENCE ]).n.Ln1:nci"l BALLARD, a citizen of theUnited States, and

a resident of El in, inthe county of Van Wert and State oi Ohio, haveinvented a new and Improved Valve, of which the following is a full,clear, and exact description.

This invention relates to new and useful improvements in" valves, moreespecially di' rected to valves as used in oil-wells, althou h theinvention is not limited to such, as t e adaptation of the improvementsto valvesin l l be apparent from the annexed description.

The barrel or cylinder of oil-wells us'ually contains two valves. Thebottom or standing valve, as it is termed, is stationary and coacts withan upper reciprocating valve in raising the oil through the well-tube tothe surface of the ground. It is often necessary to remove these valvesto renew the leathers, &c., which is ordinarily accomplished by drawingout the upper reciprocating valve by the rods connecting it andreplacing the valve with a tap adapted to screw on the lower extremityof the bottom A rod, after which the rods are lowered and turned untilthe tap and standing valve are securely threaded together, when it maybe These operations require considerable time and delay, as well aswork, which it is the object of this invention to overcome.

Reference is to behad to theaccompanying drawings, forming a part ofthis speciiication, in which similar characters of reference indicatecorresponding parts in all the gures.

Figure 1 is' an elevational view of the standing and reciprocatingvalves of a Well, disclosing the nature of my im rovements, the valvesbeing connected to et er for withdrawing the standing valve om orreplacing it in the pump-barrel. larged elevational view of theintermediate mechanism shown in Fig. 1, and Fig. 3 is a central verticalsection of the same on the line 3 3 of Fig. 2.

Referring to the drawings, the numeral 1 indicates the upper orreciprocating valve of an oil or other well, the valve being of theusual or other preferred construction.

2 is the bottom or standing valve of the usual construction,'whichcoacts with the valve 1 in raising the oil through the oil-tube to thesurface of the ground.

'Forming a permanent art of the valve 1 and removably connecte to itslower end is va device comprising an enlarged socket 3,

interiorly threaded, adapting it to be screwed onto the valve 1 andhaving a transverse opening 4 communicating with the interior of thesocket 3. At,each side of the opening 4 attened faces'' areprovided,affording means to screw'and unscrew thesocke't 3 in place. Downwardlyextending 'from the socket 3 is a threadedshank 6, preferably made as anintegral part and carrying at its lower end a tap 7 of reduced diameter.This construction providesva shoulder joining the shank and tap, againstwhich a jam-nut 8 in threaded engagement with the tap abuts. Before lthenut 8 is screwed to position a sleeve 9, formed with a nut 10 at its uper end, is threaded onto the. shank 6. T 's sleeve, as shown, isthickened at its lower end and provided with a series of longitudinalgrooves V11, dividing it into a plurality of i I extending jaws 12,vrsaid jaws belng of such proportions as to grasp the cage ofthestanding valve, and thus compelling the sleeve to remain stationarywhile the'shank 6 is being amaged by coming in contact,

as in case the rods should break and precipitate the valves together. Itis also sometimes necessary to strike the valves together, as when theballs conned in the cages become stuck or unseated and the pump refusesto work the sleeve Vwill in this instance fully protect the ta vand alsothe threads in the upper end of t e standing valve.

In placing the valves in the barrel of the pump the standing valve isdropped into the well-tubing and acquires lsufficient momentum tosecurely drive it into its seat. The working or lu per valve afterhaving the sleeve screwe contact with the jam-nut and covering the tapis connected by the usual rods at its upper end and lowered thereby intothe well until in operative osition, when the pump is ready for use. Wenit is for any reason desirable to remove the lower or standing valve,the working valve is lowered until the sleeve is seated thereon, withthe jaws engaging at the sides between the bars of the cage. By nowturning the rods in the proper direction IOO down on the shank until inl IIO labor.

I 'I the sleeve isscrewed upwardly on the shank,

w11icl1,in effect, .projectsthe tap -and threads it into the end of thestanding valve. 4Both valves can now be drawn from the well by-:therods, thus materially 'saving in time and It is obvious that( variousimmaterial changes may be made inthe construction hereinbefore describedwithout .departing from the spirit of my'invcntiom yand I consider thatI amentit'ledto such modifications as fall within the scopeof theannexed claims.A f 'l i Having thus described my invention, I claim asnew and desire to secure Letters Patent- 1. The combination of an upperand lower valve, a threaded shank ixed to theflower end of the uppervalve and forming a permanent art thereof, a sleevein threaded'engaement' with the shank, jaws carried by lt e sleeve, `and threaded meanscoacting with `the'jaws to connect thelvalves together.

2. The combination of an upper and lower valve, a threaded shank xed tothe lower [end of .theupper valve and forming a permanent part thereof,a tap extending from the lower end. of the shank', a sleeve in threadedlto engage av second val-ve .Where-by 'the tap may be screwed .thereinfor the purpose described.

In testimony whereof-Phave signed my name to this specicationin theVpresence -of ttwo subscribing witnesses.
